You can't possibly mean an Array, because an Array doesn't know anything about going to databases or cacheing. An Array is just a list of stuff. You might mean an ActiveRecord Association collection object, which behaves a lot like an array, but also has some 'magic' ActiveRecord behavior on it. The fact that, as far as I know, there's no actual class name for this AR association magic collection object, makes things rather confusing, I agree. I think it's just some proxy methods singleton-added to an Array, leaving us without a good name to call what it is, making things confusing. Or if it really is a class, I don't know what it's called cause it's not mentioned in the docs. This is a kind of a-bit-too-clever ruby hacking that Rails, IMHO, uses sometimes when it doesn't really have to, making things somewhat more confusing than they need to be. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
